How to print large diagram?

[micdev42]

I have my diagram page size set to A3 and my diagram spans multiple pages.
How do I print this (scaled down) on 1 page of A3?
As an aside, how does custome page size work?

There is precious little help in the application to explain it and about the same in the help file.

Thanks
Michael
